SUBWAY CONSTRUCTION.

Application filed April 1, 1913.

To all whom it may concern:

Be it known that I, ALPHoNsUs L. DRUM, a citizen of the United States,residing at Highland Park, in the county of Lake and State of Illinois,have invented certain new and useful Improvements in SubwayOonstruction, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to subway construction.

One of the objects thereof is to provide a practical construction forsubways having a capacity for handling extreme passenger trafiic withoutcongestion.

Another object is to provide a subway station of simple form in whichthe passenger traflic is readily handled Without inconvenience to thepassengers and in which the space for the construction is economicallyused.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings, in which is shown one of various possibleembodiments of this invention, Figure 1 is a plan of a construction forsubways; F ig. 2 is a plan of the station construction of the sub wayshown in Fig. 1; Fig. 3 is a cross-section along the line XX of Fig. 1;Fig. 1 is a cross-section along the line YY of Fig. 2.

Similar reference characters refer to similar parts throughout thevarious views.

Referring now to Fig. 1 of the drawings, there are shown a plurality ofthrough tracks 1, 1. and 2, 2, the former being preferably used forlocal train traffic and the latter tracks for express trains. In thisfigure there are shown, in somewhat diagrammatic form, two consecutivestations, 3 and 4, traversed by these tracks. These stations may beconsidered representative of a large number through which these trackspass, and if desired local stations communicating with the outer tracksonly may be interposed in the system.

At each of the stations shown there are Specification of Letters Patent.

Serial No. 758,100.

provided three island platforms, 5, 6 and 7 serving for the loading andunloading of the trains and positioned at about the floor level of carson the tracks. The station is provided at a higher level, as bestindicated in the sectional views, with longitudinal platforms or walks,8 and f), substantially registering with the sidewalks of the streetabove and extending over the outer tracks 1. These platforms areconnected by the transverse galleries 10 substantially at opposite endsof the station and a wider transverse platform, or promenade, 11. Fromthe latter platform suitable stairways 12 lead to the station platformsand are protected by rails, gates or other devices, as indicated at 13,to insure prepayment of fare. These Stairways, if desired, may be of theescalator type and similar stairways lead from the island platforms tothe upper level, as indicated at 1 1 and 15. These various points ofcommunication with the several island platforms are so spaced inposition and so ample in capacity as to insure the even flow of currentsof passengers without a tendency to congestion and the properdistribution upon the several platforms.

The several tracks 1 and 2 extend between the various stations at asubstantially constant depth below the street level and thus provide anample air space and it is to be noted that the platforms 8 and 9 extendcontinuously from station to station. One advantage due to thisconstruction lies in the convenience to passengers whereby upon leavingthe trains they may walk substantially to their destination withoutinconvenience due to encountering the traflic of busy streets orinclement weather conditions. Another and even more important advantage,however, lies in the following feature: By the construction of station4:, which is substantially identical with station 3, it will be seenthat the passenger tratlic is readily guided between the mezzanine leveland the station platform level in either direction. From the abovelevel, however, to the street there would, unless special means wereprovided, be a tendency to congestion which would be even aggravated bythe large passenger capacity of these stations. There are here provided,however, from the longitudinal platforms 8 and 9, as well as lateralextensions 16 and 17, at the various street corners, a large number ofexits 18 whereby the passengers may be received from the street level ordischarged thereto at an extremely large number of points. Due to thefact that the passengers are permitted, by the construction abovedescribed to walk to their precise destination along the route from thenearest station and even to a point offset from the route by the lateralextensions, the passengers are not discharged through 0011- strictedpassages in a highly localized area I but are evenly distributed alongthe entire route and adjacent sections. In like manner, the enteringpassengers are drawn from an equally large area through an equally amplenumber of inlets. v

It is to be noted that if desired the longitudinal or through platforms8 and 9 may be provided throughout a portion of their width with movingsidewalks, diagrammatically indicated at 19. It will also be seen thatby these relatively elevated longitudinal platforms at each station, thenecessity for platforms outside the local tracks is done away with, thuspermitting the tracks to be properly spread and spaced at each stationwithout reaching the building line of the street. Between stations thetracks may be converged into closer relation, as indicated, if desired.It is also to be noted that the lateral extensions 17 of thelongitudinal platforms may be carried a block or more beneath thesidewalks of cross streets, as 20, to another subway, a station of whichis diagrammatically indicated at 21, thus providing a covered medium oftransfer from a station of one subway to that of another. If desired,suitable gates, as 22, may be pro vided in this extension whereby faresmay be collected from pedestrians passing from one subway to the other.

The method of use of the above construc tion has been in large partexplained. It

- may be noted that the passengers may enter the system at any one ofthe various stairways 18 and walk to the nearest station, either by theextensions 16 or through platforms 8 and 9, as may be necessary. At thestation, entrance is gained to the island platforms as by the stairs orescalators 12. The discharged passengers are accommodated by theStairways 14 and 15 and pass through the upper platforms to theirdestinations.

As many changes could be made in the above construction. and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:
